Tom & NMGLUGers, I found some control for system sounds in my audio mixer controls, pavucontrol and pulse audio. I use the panel icon for sound, go to audio mixer and then, "Playback" and look for system sounds. I turned mine down a bit, but do not have the problem Tom has with high volume and pitch for system sounds. this would be a start, but not definitive. Also I am now on a desktop, but pavucontrol from the panel does work in laptops, from past experience. Thank you, Ted P On Sat, Jun 11, 2022 at 5:19 PM Tom Ashcraft <trailerdog234@comcast.net> wrote:

First thing to figure out is whether this sound is the "system beep". I had a Dell Laptop some years back where the system beep was crazy loud. I don't know why a manufacturer would do that, but sometimes they do. If you type this: echo -e \\a (try it a couple of times, for me it didn't work the first time) does it make the same annoying loud beep? Try: sudo rmmod pcspkr and if it's the system beep, you probably won't hear it any more. I wrote about that here: https://shallowsky.com/blog/linux/taming-system-beep.html On that Dell with the loud beep, I didn't want to remove it entirely (it's useful in vim and in some other contexts). My solution was this: amixer -q -c 0 set Beep 5 I don't know if that still works under pulseaudio; I wasn't using pulseaudio on that machine. You can also use xset b volume pitch duration to make the system beep quieter, shorter and higher: if you make it short enough and high enough, it'll just be a subtle click. But that only works under X and might not help with the shutdown tone. Here are some other ways to get rid of the system beep: https://linuxconfig.org/turn-off-beep-bell-on-linux-terminal ...Akkana
Thank you Ted and Akkana. Whenever my levels of Linux experience and imagination fail me and I receive a response to a nmglug question from either of you I always learn something new and useful. Usually, more than one thing. So I've been through everything both of you have mentioned and I've achieved partial success. That is, I've identified three or four methods all of which appear to be functional with respect to turning off, or at least dramatically quieting, the intermittent instances of beeps associated with logging out. I'll have to sift through my notes and recount these later when I have more time. Also there are a couple of fairly new Arch wiki pages I've found that go a long way towards reiterating and clarifying things for me. Again, perhaps more on that later. But the most glaring and mystifying issue, i.e. the (loudest) beep upon unplugging and replugging the exernal power supply/battery charger remains. Nothing makes it go away. My best guess is that because this is a laptop there is no dedicated beep speaker and everything does have to go through the sound card; and, the final nut I have to turn is figuring out how to identify which ALSA channel, if any, is responsible for delivering the offending behavior. Despite my best but limited efforts so far it's just not clearly apparent. Configuring ALSA competently is a bit beyond my pay grade but I expect the required information may be found somewhere among these links: https://wiki.archlinux.org/title/Disable_PC_speaker_beep https://wiki.archlinux.org/title/Advanced_Linux_Sound_Architecture#Unmuting_... https://en.wikipedia.org/wiki/Advanced_Linux_Sound_Architecture#Applications Tom On 6/11/22 17:18, Tom Ashcraft wrote:

This seems to be an Acer (mis)feature. When I googled acer netbook loud beep plugging unplugging power I got lots of hits. It appears that the (mis)feature is called "Power Control Beep" and many Acers have an option in BIOS to disable it, so look there first. If not, try a web search with your actual machine model (you didn't tell us the model, you just said "Acer netbook") along with Linux and "Power Control Beep", and you might find advice specific to that model. Also, some Windows users seem to be seeing a channel in their volume control settings for "PC Speaker", so maybe Linux has that too. You might run alsamixer or ulsamixergui to see if alsa has a channel like that, in which case you could set the volume on that channel down to zero. If alsamixer or alsamixergui don't see such a channel, try pavucontrol, which works at a higher level (pulseaudio vs. alsa) and might show a different set of controls. Good luck! ...Akkana
Tom & NMGLUGers, It may be a BIOS signal. Luckily the beep when I select "Logout" from the GUI is low volume on the Dell desktop I am using now. Running 'top' in commandline while I do the logout shows the same Xorg and webcontent activity I am using and no other new action at the same time. I wonder if it is an Acer bios issue. There are several "Acer Beep" questions posted on the web, but none quite like yours. Have you search the bios setting and checked the status of the bios battery?

Thank you Akkana and Ted, my problem with the beeps has ended. Your suggestions, observations and questions were on point and indispensable for helping me locate (and comprehend) some exact instructions for how to resolve the issue. Here's how it went: On 6/12/22 19:08, Ted Pomeroy wrote:

Have you searched the bios settings Yes, more than once, but nothing useful accessible there. ...and checked the status of the bios battery? Hmm. Again, no access via bios, and I suspect not particularly relevant at the present time as I never seem to hear anything like "beep codes", only a single beep. But that's an interesting question that might in the future be useful to have an answer for. Is there a way to you know of to access status of the bios battery from a regular terminal command line?

As above, been there done that.

Bingo. I thought the neofetch host line (AO722) that I provided in my original post was sufficiently clear and obvious, but I suppose I might better have been more direct or explicit and thorough. The label on the bottom of the computer says Aspire one 722-BZ480 and MODEL NO: P1VE6. As it turns out 'Aspire one 722' was the most productive search string (or the most productive portion thereof) -- just as you suggest it might be.
...You might run alsamixer or ulsamixergui to see if alsa has a channel like that, in which case you could set the volume on that channel down to zero. If alsamixer or alsamixergui don't see such a channel...
Alsamixer *does* have a beep channel, just as you suggested it might in your *first* response to my *first* post. I just couldn't quite figure out how to find it, didn't correctly comprehend the manner in which it remained obscure. A case of "out of sight out of mind". The rest of the story: Pertinent results from Google search terms 'linux beep acer aspire one 722-BZ480', the exact links: https://www.google.com/search?hl=en&q=linux+beep+acer+aspire+one+722-BZ480 https://ubuntuforums.org/showthread.php?t=1824927 https://housegeekatheart.blogspot.com/2011/10/disable-ac-adaptor-beep-in-por... Excerpted from the second link, the clearest and most effective description I needed to be able to deal with ALSA. It works exactly as described: This is the answer to the million dollar question: disable the AC adapter / power cord beep in Acer Aspire One AO722 netbook in Ubuntu 11.10. ... Then use the utility # alsamixer For portables there are no separate system speakers for the system beep, therefore the desktop methods won't work. For some portables, there are two devices, one for the digital HDMI and one for the analog speaker and headphones. You have to pick the correct one for the volume settings. For the AO722, use F6 to pick the conexant sound card, rather than the first HDMI sound card. Then use the arrow keys to get to the beep column. Type m to toggle the muting status. The heart attack beep will be off when the power cord is attached or removed. But the beep is not altogether muted. The beep volume seems to be coupled to the master volume or the alert volume.
